BopoTaco: Bopomofo Typing
Zhuyin drills, TBCL-graded
Free · In‑App Purchases
Launch price through September 30, 2026. The bopomofo course and 1-minute test stay free. Pro is a one-time purchase, not a subscription. No ads, no tracking, no account.
Learn Mandarin the way Taiwan actually types it — with bopomofo (zhuyin), the phonetic system on every keyboard there.
No ads. No data collection. No account.
■ Learn bopomofo typing, free
A few spare minutes is enough for a round.
All 37 bopomofo symbols, the tones and the sounds, one lesson at a time.
Once you have finished them, the All Symbols drill keeps them sharp, and any lesson can be replayed whenever you want.
■ 1,517 lessons of characters and words, most common first
Characters and words come from Taiwan's Ministry of Education dictionary, graded 1–7 against the Taiwan Benchmarks for the Chinese Language (TBCL), then cut into lessons of ten in the order they are actually used.
You always know which lesson you are on and how many are left — no guessing what to practise.
■ Watch your speed
Keys per minute (KPM) and accuracy, on screen as you type.
The timed test tells you exactly how fast you are right now.
■ Dictation mode
Audio only — the prompt stays hidden. Listen, then type.
When Regular mode stops being a challenge, this is the stage above it. Every bopomofo, character and word lesson, and the timed test.
■ Statistics that show you the weak spots
A per-symbol accuracy heatmap: the sounds you are shaky on, at a glance.
The pairs you most often confuse, the syllables you keep missing, how much you have practised and where it is heading — enough to find a weakness and clear it.
